APPARATUS FOR INSURING INTIMATE 'ADMIXTURE MATTER AND A LIQUID PRODUCT.

0F PULVERULENT OB GRANULAR Application filed December 4, 1924, Serial No. 754,004, and. in Be1gium December 12, 1923;

i This invention relatesto apparatus for ettecting the admixture of certain substances with water or other fluid, and more particularly to apparatus of the'typ'e comprising aserie's of superimposed plates or pans to successively receive material and fluid to be admixed by stirre'rs set at an angle to direct the mixed or diluted substances to outlets in the trays.

' Actual use and experiment. hasdemon strated that apparatus in which plastic, sticky or gummy or greasy materials such as clay, which absorb water very slowly, are stirred on the successive plates or pans, by rotating stirring blades, are unsuitable for the purpose for the reason thatlin the upper pans especially, th'e solid or heavy inert material on the fixed base is com pressed'by theblades into such a hard mass that it eventually clogs and arrests rotation of the blades and'operation ot the apparatus besides clogging the discharge openings.

Actual use and experiment have, however, demonstrated that the objectionsv above re terred to can be obviated .by rotating the pan to direct pans against fixed blades, thus making use of the inertia, and setting of fixed blades at an angle, alternately near the centre of one pan and near the periphery of the next the material to the discharge opening at those parts; the blades being mounted in such manner that the furrows, formed by one row of bla e are covered over by the next row of blades, and, further, providing inclines furnished with nozzles, disposedabove each of the plates, or pans and operating in conjunction with compressed air to ensure projection of liquid in very fine particles onto the surfaces of the material as it is exposed by, subsequently covered by. another blade; the small correct quantity of water. being thereby thoroughly absorbed. that unless such precautionsare stringently observed that the outer surfaces of grains of clay or similar substances are too wet, whilst their interiors are too dry.

A constructional :torm of the invention is shown by way of example in the accompanying drawing, in which a blade and It has been found Figure 7 1 shows I diagrammatically the As seen in the'drawingthe apparatus com prises a structure formed by two vertical supports 1 and 2 joinedcby a cross-piece 3.I

At the'upper part of these "members are secured bearings for supporting a horizontal shaft et,ficarrying the fast andloose driving pulleys, 5' and 6, and aconical pinion 7 for transmitting'the rotatory movement of the horizontal shaft 1- to a vertical shaft 8 on which is keyed 'a' second conical pinlon 9 gearing with theflpinion 7. The ratio of these two pinions is preferably such as to reduce speed of rotation of the vertical shaft .8 in respect to that of the" horizontal shaft 1.

The vertical arm 8 turns at its lower end in a socket 10 integral with a base 11 on which the two supports of the structure p 7 F80 rest. 7 s I p v On the vertical arm 8 are keyed thecir- -cular"plates 12, 13 and 1A, forming vessels to contain the material tobe treated, the latter, being let in on the highest plate 12 and passing successively on [the intermediate plate 18then on the lower plate 14:, For

this purpose the topplate 12 shows on the "bottom holes made near its centre andv com-I municating with channels 15which lead into the intermediate plate 13. The latter also hasholes on the periphery of its base and provided-with channels 16'which lead into the lower plate 14. This last one is similar whole of the apparatus in vertical longitudi- V to the top plate, 1ts holes being formed at the centre and theichannels 17 whi'ch'comi munic'ate with these holes lead into a vat 18 integral with the base 11 and 'whose di-' ameter is slightly/larger than 'that of the plates.

Circular rings 19, 20 and 21 or iron "plate: are secured on the two supports of the struc ture above each of the plates 12, 13 and 14:.

' rigs. o

staggeredon the arms 22 so as to scoop turrows alternately open and closed in the material so as to present new surfaces for the pi e ection of the liquid. (m the other hand the blades may be secured or receive a variable and adjustable inclination according to the chz ivery so to prevent the material overflowing the plates. For this purpose the rods 23, on which are mounted the blades,

are connected at their top end to cranks 25 and 7) articulated on a bar 25 which is mounted and may slide in collars fixed on the rings 19, 20 and 21 and on the fixed sleeves formedby the Each of the bars 26 is disposed parallel to the bladecarrying arms 22 and the end passing out of the structure forms an operating handle. The blades of the intermediate plate 13 mounted in the, radius of the peripheral holes are in the shape of cups 27 whose outer edge is tangential to the wall of the plate and retains the material brought to the centre by the other blades 24; until the holes are brought opposite the cups the material then passing normally through these holes and into the channels 16 to fall, on to the lower plate 14:. 7

At the lower part of the vertical shaft 8 is keyed a hub on which are secured blades 28 which dip into the vessel 18 and rotate with the shaft 8. These blades are conveniently c'urvedinwards following the sense of rotation and bent so as to stir up the material, to convey and distribute it regularly at. four holes 29 formed in the base 11 forming the bottom of the vessel 18. Each of the holes29-communicates with an evacuationchannel 30 provided with an adjustable trap-door opening, operated from outside and permitting the distribution of the delivery at will, to feed the different appara tus which require ditlerent outputs or finally to put the treated material directly into bags. i V

; The projection of the liquid is assured by compressed air nozzles 31 disposed betweeneach, of the blade-carrying arms, and the supply of the liquid is maintained by means o1 a reservoir under a greater pressure than the air. A regulatingmember in, checking 'more or less the. delivery of the liquid, permits of putting thelatter in the positiono-f normal equihbrlum in relation to the manometrical pressure supplied by the compressed air generator. in the present meth 0d of regulation, the air pressure.mayvary between 300 and 800 min. of water column.

Finally, the material t0 be treated is brought onto the top plate 12 by a vibrating distributor 32 giving three'adjustments for the delivery. A delivery blade is secured in any convenient way on the top ring 19 and it is formed so as to prevent the material in treatment on the top plate 12 returning relative to the distributor outlet during the rotatory movement of the said plate.

above said, furrows alternatively open and closed, so as to present new surfaces to the projection of the liquid. The blades are set so as to conduct the material towards the holes made at the centre of the plate, so that the treated materials on the first plate 12 arrive on the intermediate plate 18 Whose blades are set so as to conduct the materials towards the periphery.

lvhen the materials have passed successively on the three superimposed rotatable plates, in which'they have been subjected to the action of the fixed bladesand the projection otthe liquid, which thus uniformly impregnates them, they arrive in the fixed vessel 18 by way or the channels 17. They are thus conveyed by the inward-curved blades 28 keyed on the vertical shaft which distributes teem regularly to the four evacuation channels 80 to prevent their heaping up and compression.

It is understood that the arrangement shown is given only by way of example and that the constructional "forms, details of construction, accessories and dimensions may vary according to the circumstances, with-.

pans for the material to be treated and having discharge openings therein disposed alternately near the centre and near the periphery in adjacent pans, stationary radially disposed sets of blades depended within the pans'and inclined towards theirdischarge openings, the blades in adjacent sets being relatively staggered in a radial direction, and a liquid supply nozzle disposed immediately in rear of each blade and directed to- Wards the part of the pan where the material is displaced by the appurtenant blade.

Apparatus of the type referred to, comprising superimposed rotatably mounted pans for the material to be treated and having discharge openings therein disposed alternately near the centre and near the periphery inadjacent pans, stationary radially disposed sets of blades depended Within the 30 pans and inclined towards their discharge openings, the blades in adjacent sets being relatively staggered in aradial direction,

means forrvarying the inclination of said the material is displaced by the appurtenant blade.
